Abstract: A method and system for generating a completed payment document ready for signature in image form and enabling signature in image form, storing the image and providing a printed copy of the document including the signature. A write input device for showing the image and enabling the signature includes a transparent interactive digitizing element with writing stylus, a display module positioned beneath the digitizing element and visible therethrough, and optionally a magnetic stripe reader for providing document-related information for the display. The device is embodied in a system which also includes a point of sale terminal, a printer for printing records of transactions processed by the system and a controller operatively coupled to other elements of the system.

Abstract: A method and apparatus for providing and using a variable format, configuration and location keyboard image which enables a digitizing device to present a different keyboard configuration and/or location to each user so that detection by an unauthorized viewer of a personal identification number (PIN) or other secret identification number during entry will become significantly more difficult. The presentation may include a random or scrambled keyboard entry image for each customer, and a single or set of customer preselected images that will be tied to the customer's account number which is read from the magnetic strip on a personal card. In addition to the keyboard, the device provides a single write surface for capturing a signature entry so that the two security features are incorporated in a single device.
